MACHINE FOR TURNING CYLINDERS 0F WOOD.

Specification of Letters Patent No.

To all 'whom it may concern Be it known that I, INCREASE S. IVAITE, ofHubbardston, in the county of Worcester and State of Massachusetts, haveinvented a new and useful Machine for Turning Cylinders or Various otherArticles of Vood; and I do hereby declare that the same is fullydescribed and represented in the following specification and theaccompanying drawings, letters, figures, and references thereof.

Of the said drawings, Figure l represents a top view of my said machine.Fig. 2, a side elevation of it.

In the said drawings A represents a horizontal shaft supported bysuitable bearings or pivots, B, C, that are sustained in position by aproper frame, D. This shaft carries two circular heads E, F, which arefixed upon it at a proper distance apart and parallel to each other,eachv being at right angles to the shaft. One of these heads, viz., E,has a series of centers G, G', G2, or pivots projecting from its innerside and near its periphery and at equal distances apart from oneanother, and respectively in line with a similar number of mandrels G,G', G2, H, H, I-I2, applied to the other head F and each made to freelyrotate like the arbor of a lathe, and be capable of sliding through theplate in a longitudinal direction. Each of these mandrels is sustainedby the circular head F, and a metallic support piece I, shaped andattached to the To each mandrel, and to the head a spring K, K2, or K2,is applied, the spring being attached at one end to the head, and beingforked at its other end, and made to work or extend into a groove a, cutaround in the front part of the mandrel. On the opposite end of each ofthe mandrels is a wheel L, and each mandrel has a screw M and a gear Nfixed upon it, as seen in the drawings, the said gear having a retainingspring pawl 0, applied to it and the head.

On the inner side of the frame D and within the path of rotation of thewheel L is an inclined cam plate P, shaped as seen in the drawings, andso arranged as to actagainst the inner side of the wheel L of eachmandrel and force the mandrel backward so as to relieve the turnedarticle from it, and move it back a sufficient distance for it toreceive and grasp a piece of wood to be turned. The several pieces ofwood to be 10,193, dated November 1, 1853.

turned in succession are seen at Q, Q, Q, asplaced wit-hin a box orhopper R. The said hopper is arranged as seen in the drawings, and ismade as represented in Figs. 3 and 4, which respectively are side andfront views of it, it being made so open at the lower part of its frontside and at its end as to allow the lowermost of t-he pieces of wood Q,Q, to remove from it by the action of one of the mandrels and the centerG, G', or G2 thereof, while the rotary heads E, F, are in revolution.The hopper shouldl be so arranged that at the moment the wheel L passesentirely beyond the upper end of the cam I), the axis of the lowestpiece of wood Q should be in line with the axis of one of the mandrelsand one of its centers G, G, or G2, for at such time the mandrel isreleased from the cam and is thrown forward by the action of its spring.The spring advances it toward and against the piece of wood so as tocause it not only to smartly move the piece of wood againstl the centerG or G', but to fix the mandrel to the wood, the inner end of themandrel being provided with spurs b, b, such as will so fasten themandrel to the woods as to cause the wood to turn with the mandrel whenthe latter is put in revolution.

A rotating cutter wheel or cylinder (as it is sometimes termed,) isplaced on a horizontal shaft T, which is disposed with respect to theheads, E, F, as seen in the drawings. This cutter wheel may be formed orhave the edges of its cutters so formed as to render it capable ofturning a piece of wood in a cylindrical shape or in any other shapewhich in transverse section is circular, as a piano-forte leg forinstance. This shaft T is put in rotation by means of a belt from anysuitable driving power made to pass over a pulley U, fixedv on the saidshaft. Nearly in line with the shaft T is another shaft V, arranged asseen in Fig. l, and having a gear W, fixed on its inner end as shown insaid figure, such gear being made to match with the gear N, hereinbeforementioned, and to engage with said gear and put it in rotation when thetwo' are brought into contact.

The shaft V of the gear W receives its motion by means of a gear X,fixed upon its outer end, and made to engage with a pinion gear Y, fixedon a driving shaft Z, put in rotation by a band made to work over adriving pulley A', fixed on the said shaft.

The gear X engages with a gear B', which is made to convey motion to orengage with another gear C', fixed upon a shaft D', arranged as seen inFigs. l and 2. On the said shaft D there is a friction roller or wheelE', whose periphery is borne up against the periphery of the circularhead F, by means of a weighted lever F'.

Fig. 5 is a 'vertical sectionjaken through the head F, the roller E',and exhibits the lever F', its fulcrum and supporting strut. The innerend of the shaft D turns in the said lever, while the upper end of thelever is supported on a fulcrum G', extended from a strut H', that isprojected from the cross bar of the frame D, as seen in Figs. l and 5.

In Fig. 6, I have exhibited an external side view of the head E, and itsappurtenances, which head is provided as seen in thedrawings with studsI', K', L', each of which is placed near to some one of the mandrels,there being a stud to each mandrel and such stud being so situa@ withregard to it as to come in contact with a Stop plate M' and stop therotation of the heads E, F, when the mandrel is carried into a suitableposition, for the rotary cutter vwheel S to operate on the wood held byit.v This sto-pplate (a top view of which is represented in Fig. 7)turns on a fulcrum pin d, screwed into the top surface of a tubular armN. The front end of this stop plate, or that which has a smallprojection O', extended from it, is forced toward the head F by a springP'. (See Fig. 1)., This projection O' extends between the threads of thescrew N, and consequentlywhen themandrel is put in revolution, suchscrew will cause the stop-plate M to be turned or moved laterally untilit passes from under the stud I', K', or L', that may be resting on it,and so asto remove,allliindrance to the further rotary movement, of theshaft A and its heads. Now during the time that such stop plate is beingso moved, the mandrel is being rotated by the gear IV, which engageswith and turns the gear N of said mandrel. Thus is effected the rotationof the block of woopl which is to be turned, such rotation taking placewhile the cutter wheel is in operation on it. As soon as the stop plateM passes from under the stud as described, the shaft A will be put inrotation by the action of the friction roller E' against the peripheryof the head F. This takes away from the cutter S the piece of wood thathas` just been turned and brings up to or carries toward the said cutteranother piece of wood to be turned, which latter piece has been seizedby a mandrel and its center and removed from the hopper. As soon as saidpiece is removed from the hopper, the whole number of pieces within thehopper fall downward and dispose themselves so that when the neXtmandrel comes up to the lower one, it will seize and remove it in asimilar manner. Vhen a mandrel holding a piece of wood is retracted orpulled backward by the cam plate P, the wood will drop out of themachine. Thus pieces of wood may be successively operated upon or takenfrom the hopper and turned and discharged from the machine.

Having thus described my invention, what I claim is as follows:

I claim the combination composed of the feeding hopper, the series ofrotary mandrels and centers applied to the shaft A, the revolving cutteror cutter cylinder S, .mechanism for giving to each mandrel an endwisemovement, backward and forward as described, mechanism for arresting therotary movement of the shaft A, or the heads E, F, during the timenecessary for the operation of the cutter or cutter wheel S, on eachpiece of wood, and finally a mechanism for rotating the shaft A and itstwo heads all substantially as above described; the mechanism formoving` each mandrel endwise in manner and for the purpose described,being the spring K, the wheel L, and cam plate P, as described, that forrotating the mandrel, being the gear N and the gear WV on the shaft Y,put in revolution as described; that for arresting the rotation of theshaft A during the time necessary to turn down an article being thestuds I', K', or L', stop plate M', and the screw applied to eachmandrel and made to operate aS specified; and finally, that for rotatingthe shaft A, being the friction roller F', made to operate against theperiphery of the 4 circular head F and to be rotated and borne againstsaid head substantially as herein before set forth.

In testimony whereof I have hereto set my signature this eleventh day ofApril, A. D. 1853.
